Loads data to the controller periodically. Usage:

var url = "dynamicallyAPI/data";

// Load data from the url with liveLoad() API.
// Set callback
// Specify loading time

controller.liveLoad( url, liveLoadCallback, 50000 );

function liveLoadCallback () {

        console.log("Load data event happens.");

}

// use closeLiveLoader API to close live load function
// controller.closeLiveLoader();
